POWERbreathe is a scientifically proven Inspiratory Muscle Training (IMT) device, developed by leading scientists for improving the strength and endurance of the muscles used to breathe in, primarily the diaphragm and intercostals / rib cage muscles.

As with any other muscle, respiratory muscles can be trained so that they are more resistant to fatigue. This resistance to fatigue results in reduced breathlessness and enhanced exericse tolerance. 

POWERbreathe Classic uses scientifically proven Pressure Threshold Training. This provides a specific and consistent pressure to train against. When breathing in through POWERbreathe the load calibrated spring provides the resistance.  

Resistance Loads &nbsp

Level 1 10cmH2O 10cmH2O 10cmH2O
Level 2 20cmH2O 30cmH2O 40cmH2O
Level 3 30cmH2O 50cmH2O 70cmH2O
Level 4 40cmH2O 70cmH2O 100cmH2O
Level 5 50cmH2O 90cmH2O 130cmH2O
Level 6 60cmH2O 110cmH2O 160cmH2O
Level 7 70cmH2O 130cmH2O 190cmH2O
Level 8 80cmH2O 150cmH2O 220cmH2O
Level 9 90cmH2O 170cmH2O 250cmH2O


Please note: Heavy resistance is only for those who have reached maximum loading on a medium resistance model. If you start with a heavy resistance model, you will not experience the benefits of POWERbreathe training and may struggle to acheive higher levels due to the faster progression between loads.


Precise load settings may vary due to: (1) the analogue nature of the calibrated spring tensioner and the precision with which the load is selected; (2) a small effect of inspiratory flow rate upon spring compression such that high inspiratory flow rates lead to greater spring compression, and a small increase in load.

This effect is common to all spring loaded devices, and its size is magnified by increasing spring range (it is larger in a spring with a maximum range of 90cmH2O compared with one with half this range), it is also greater at lower absolute load settings.

Choose Light Resistance:

  • If you exercise / are physically active for less than 2.5 hours per week and have no breathing problems
  • If you exercise / are physically active for less than 2.5 hours per week and have breathing problems - minor/moderate
  • If you exercise / are physically active for more than 2.5 hours per week and have severe breathing problems

Choose Medium Resistance:

  • If you exercise / are physically active for more than 2.5 hours per week and have no breathing problems
  • If you exercise / are physically active for more than 2.5 hours per week and have some breathing problems that are not severe

Choose Heavy Resistance:

  • Only if you have reached the highest load setting on a POWERbreathe Medium Resistance model first.

Keeping a record of the training level reached and the number of breaths successfully completed per session will help you analyse your progress.

How to use:

  1. Put the nose-clip on so that it pushes your nostrils together (this is optional but prevents you from breathing in through your nose).
  2. Breathe in quickly and forcefully through your POWERbreathe for 30 breaths twice a day (preferably morning and night so you allow your inspiratory muscles time to recover in between sessions). This is the scientifially proven training regimen.
  3. As your inspiratory muscle strength and stamina improve, adjust and increase the resistance.
  4. Within a few days your inspiratory muscles will feel stronger; within 3-weeks you’ll feel less breathless; and within 4 weeks activities will feel easier.
  5. Full instructions are provided in the accompanying user manual.


  1. Your POWERbreathe will be exposed to saliva during use. We recommend that a few times a week your POWERbreathe should be soaked in warm water for about 10 minutes (see your POWERbreathe Manual for full details).
  2. Once a week your POWERbreathe should be soaked in a mild cleansing solution instead of water, using the POWERbreathe Cleansing Tablets - only 1 tablet is required each time. 

POWERbreathe is drug free, suitable for almost anyone and should cause no harmful side effects when used properly. Please read the following precautions and contraindications to ensure that you use your POWERbreathe safely and appropriately.

If you have any doubts about POWERbreathe’s suitability, or you have a medical condition, please consult your doctor.


  • Do not make changes to any prescribed medication or prescribed treatment programme without consulting your doctor.
  • Do not use POWERbreathe if you are suffering from a ruptured eardrum.
  • To prevent the potential transmission of infections, we recommend that you do not share your POWERbreathe with other users, including family members.
  • This product is not intended to diagnose, treat, cure or prevent any disease.
  • POWERbreathe is designed for exercising your inspiratory muscles only. No other use is intended or implied.
  • Anyone who is under the age of 16 should only use POWERbreathe with supervision from an adult. POWERbreathe contains small parts and is not suitable for children under 7 years.
  • Whilst training with POWERbreathe you should feel resistance when inhaling but it should not be painful. If you should feel pain whilst using POWERbreathe, stop immediately and consult your doctor.
  • Some users may experience slight ear discomfort when training with Medic Plus, especially if they are recovering from a cold. This is caused by inadequate equalisation of pressure between the mouth and ears. If symptoms persist, please consult your doctor.
  • If you are suffering from a cold, sinusitis or respiratory tract infection, we advise that you do not use POWERbreathe until symptoms have disappeared. If in doubt, consult your doctor.
  • Refer to your Healthcare Professional before using POWERbreathe if you have any of the following conditions:
  1. A history of spontaneous pneumothorax (a collapsed lung that was not due to traumatic injury e.g. broken rib), as it may lead to a recurrence of the condition.
  2. Pulmonary hypertension o Large bullae on chest x-ray
  3. Marked osteoporosis with history of rib fractures
  4. Desaturation during or following IMT (<94%)


Inspiratory muscle training, such as training with POWERbreathe, is not recommended for patients with certain conditions, including the following:

  • Asthma patients who have low symptom perception and suffer from frequent, severe exacerbations or with an abnormally low perception of dyspnoea
  • If you are suffering from a ruptured eardrum or any other condition of the ear
  • Patients with marked elevated left ventricular end-diastolic volume and pressure
  • Patients with worsening heart failure signs and symptoms after RMT / IMT
  • If in doubt, consult your Healthcare Professional.

On my VERY limited inhale, as I have asthma, I have noticed a difference.
Review by Bella

On my VERY limited inhale, as I have asthma, I have noticed a difference. I also use it as an indicator for colds, hay fever etc. When I can’t inhale well I increase my medication. For me far better than Peak Flow, at which I am rubbish. My asthma nurse is happy for me to use Powerbreathe Wellness Edition (now LR - Light Resistance model) to control my medication.
POWERbreathe training with a cancer patient
Review by Senior Physiotherapist at The Royal Wolverhampton
Posted 2 December 2015
The doctors were really pleased with his repeat lung function tests, some of the values had improved considerably, they felt we've given him the best chance possible to making it through his transplant, and feel the Powerbreathe device has been a contributing factor to this despite us only having a small window of time to work with it.

He was using it daily from the day you dropped it off to the day he was transferred to Birmingham, and I’m confident he was going to continue with it after he left us. We had also managed to increase it up to number 4 from 1 in the few weeks he was using it.

If he comes back to us post transplant (which I have a feeling he may) I will keep you updated on his progress and possibly we may be able to arrange a review? Although this will depend very much on if he returns to us or goes straight home.
Many thanks for everything you did to help us in his management.
this device is great for people with lung disorders

This device is great for people with lung disorders like emphysema it assists with the enlargement of the lungs when the sacks are blistered or burst it can assist with the exercise program that has been set out as a task for repair of the damaged lung.
I've been using my POWERbreathe for over 17 years
Review by Donald

I've been using my POWERbreathe for over 17 years. Bought it from Birmingham University before it went on the open market.

I'm 79 years-old and it's got me through several marathons, heart surgery and other ageing complaints.

Recent lung capacity tests show I'm above average. I'm sure it's because of my years of use of the POWERbreathe.

Since my last review in 2012 I have used the power breathe on a regular basis. I recently traveled to the Himalayas on a motor cycle (Royal Enfield) adventure to the worlds Highest motor able pass- Khadung-La.I had no breathing problems, it works. I still practice and teach Taekwon-Do on a regular basis.
The benefits of training the lungs in this way is immeasurable
Review by Jude
Posted 11 September 2013
When I informed my consultants/doctors that I had purchased one they were pleased and spoke of the benefits of using it. However, they did not offer to prescribe. There needs to be a bigger campaign to bring Powerbreathe equipment and training to the health industry. My awareness of it was only because of my involvement in the fitness industry. The benefits of training the lungs in this way is immeasurable! I have found excellent results and recommend it to anyone who has breathing difficulties or those who wish to increase their lung capacity for sport or fitness. Let's get Powerbreathe equipment/training recognised and widely available in treatment plans for people who struggle to breathe!!

Very Sceptical at first, now I must admit I can see improvements
Review by Roy Partington
Posted 20 August 2013
I was very sceptical of this device when I was first recommended it, as there are a lot of devices out there that make all sorts of fantastic claims to aid your breathing at Altitude. This is one of them that now has a growing voice from well respected high altitude mountaineers, along with having been used by numerous Everest expedition climbers and also has nearly a full page dedicated to it in the fantastic book "Mountaineering Training and preparation" a book which I can most certainly highly recommend for your training....

...It just seems such a simple device to use that it is hard to believe that it can be this alone that is making these huge improvements in my breathing, but without a doubt I have only noticed these improvements since using the PowerBreathe.

It's fab for asthma but device can break
Review by Bartlebe
Posted 22 May 2013
Wonderful for asthma, has really helped me improve my peak flow levels and coupled with physio helps get air into my lungs more, improving bronchiectasis and asthma. Every asthmatic should have one, and the NHS should be ashamed of themselves for not advertising its availability more. I have though been using mine for 3/4 months and the product is very plastic, the valve sticks and gives different resistances depending on how you hold it, which means I have no idea what level I'm on (I'm supposed to be on level 5) but the resistance changes every time I touch it! Still despite that, it's well worth having. I'm just gutted I can't afford a digital one as I should imagine they are far more reliable.

Note from POWERbreathe Admin:
Thank you Bartlebe for your feedback and we’re delighted the POWERbreathe Medic has helped you with your asthma. We were sorry to hear though of your experience with the valve sticking. Obviously we value your feedback, and as it’s not a problem that we’ve heard of before, we wondered if you would mind getting in touch with us at enquiries@powerbreathe.com so that we may help. We’ll look forward to hearing from you Bartlebe, POWERbreathe.
Our patients have found it to be of great benefit

We have been using the POWERbreathe Medic for over a year as part of the pulmonary rehab programme and our patients have found it to be of great benefit and enjoy using it. We have good compliance and have found an improvement in patients’ fitness. We will continue to use the POWERbreathe Medic as an adjunct to our programme.

After only a couple of weeks I found a positive difference
Review by L Bywater
Posted 20 September 2012
On the up and up! I have now had my POWERbreathe for six weeks, I planned to see what the effects would be after then, but after only a couple of weeks I found a positive difference.
My breathing was a lot better, easier and deeper, and I felt more confident and stronger, and found I did not need to carry my blue inhaler around with me. Working with my asthma nurse, (who had not heard of POWERbreathe) I still use my medication for the asthma I developed some ten years ago. I have always been active and do mountaineering, biking and the like, and still continue to do so. So it was baffling to find my condition was starting to bother me at times, while at rest.
I use the red POWERbreathe Sport, now on my seventh week, after starting on the zero setting, now on 1.75. My peak flow readings are now averaging out at a higher reading than when I started, although technique using this is a bit iffy. All in all, after using POWERbreathe I feel very positive and I am only at the beginning.
